摘要:
A system for continuously imaging a surface of an object is provided. The system includes a drum mounted to a support frame and having an inner periphery and a hollow body for receiving the object therethrough. The hollow body has input end and output end sections, and a central rotation axis extending through the input and output end sections. The drum is drivable to rotate about the central rotation axis in a conveying mode. The system includes an optical assembly including a light source and a detector mounted to the drum, such that the optical assembly rotates along with the drum in the conveying mode. The system also includes a processor configured for processing a signal representative of a resulting light emanating from the object, thereby continuously generating an unwrapped image of the surface of the object and planarly representing the surface of the object.

A method comprises: directing a laser beam onto a side of a tube, wherein the side includes a defect; moving the tube with respect to the laser beam such that the laser beam beams onto the defect; sensing a reflection of the laser beam from the side based on the defect; computationally identifying a change between the laser beam and the reflection; computationally acting based on the change. The side can be internal or external. In other implementations, the laser beam is moved with respect to the tube such that the laser beam beams onto the defect.

The invention provides a system and method for inspecting manufactured products. The system includes an inspection apparatus, which is in communication with a central processing unit, configured with inspection and self learning module. Initially, the inspection apparatus is fed with set of exemplary products through which the inspection module captures the product specification, dimensions and the surface details. The captured data is sent to the central processing unit, where it is converted into reference data. Further, different components of the inspection apparatus self calibrate based on the received reference data and examine the manufactured products, and as part of the examination, the apparatus rejects the products which do not the match with the reference data.

In-line inspection and control system to in-situ monitor an extrudate during extrusion. A light beam illuminates a line on the outside circumference of the extrudate skin recording the curvature. A master profile of the illuminated defect-free skin is recorded and compared to successive monitoring of the illuminated skin. Differences from the comparison indicate skin and/or shape defects. A real-time feedback to automatically adjust process control hardware reduces or eliminates the skin and shape defects based on the monitoring and comparison.

There is provided an apparatus and method for inspecting a semiconductor package. The apparatus includes at least one 3D camera positioned at a first angle relative to a normal axis of the semiconductor package; and a light source configured to provide illumination for the at least one 3D camera, the light source being directed at the semiconductor package. The method includes casting a shadow of a bonded wire onto the semiconductor package; obtaining a 3D image of the semiconductor package; determining a distance S of the shadow and the bonded wire in the image; and obtaining a wire loop height H of the bonded wire.

High-speed, triangulation-based, 3-D method and system for inspecting manufactured parts and sorting the inspection parts are provided. A plurality of angularly-spaced, triangulation-based, sensor heads are located at an imaging station to simultaneously deliver focused lines of radiation onto a plurality of exterior side surfaces of the part during motion of the part relative to the focused lines to obtain corresponding arrays of reflected lines of radiation. The sensor heads simultaneously sense their corresponding arrays of reflected lines to obtain corresponding sets of 2-D profile signals. Each set of profile signals represent a 3-D view of one of the exterior side surfaces and the sets of 2-D profile signals represent a 360 panoramic composite 3-D view of the outer peripheral surface of the part.
